Dot1 is a methyl transferase that has been shown through a reporter gene to be involved in position effect variegation of gene expression in heterochrmatic regions such as telomeres and the mating type loci in yeast. This study examines the effect of mutation of DOT1 and two other proteins involved ...

Packaging of DNA into chromatin has a profound impact on gene expression. To understand how changes in chromatin influence transcription, we analyzed 165 mutants of chromatin machinery components in Saccharomyces cerevisiae. mRNA expression patterns change in 80% of mutants, always with specific eff...
